Abstract

The invention relates to a motor vehicle, comprising a body and a drive train, wherein the drive train comprises a front axle (10), a rear axle (13), a drive unit, and a gearbox (20), wherein the drive unit is designed as a hybrid drive having an internal combustion engine (16) and at least one electric machine (17, 18, 19), wherein the internal combustion engine (16) can be supplied with fuel from at least one fuel tank (21), and wherein the or each electric machine (17, 18, 19) can be supplied with electrical energy from at least one electrical energy store (22) in motorized operation, and wherein the or each fuel tank (21) and the or each electrical energy store (22) are positioned in a common section (23) of the body.

Claims

1. A motor vehicle, comprising a body and a drive train, the drive train having a front axle, a rear axle, a drive unit and a transmission, the drive unit being a hybrid drive with an internal combustion engine and at least one electric machine, the internal combustion engine being suppliable with fuel from at least one fuel tank, and the electric machine being suppliable with electric energy from at least one electric energy accumulator in the motor mode, the fuel tank and the electric energy accumulator being positioned in a common section of the body, the internal combustion engine being arranged in a mid-engine arrangement rearward of the front axle and forward of the rear axle and rearward of the common section of the body, in which the fuel tank and the electric energy accumulator are positioned.

2. The motor vehicle of claim 1, wherein the at least one electric machine comprises at least one electric machine comprises at least one electric machine assigned to the front axle.

3. The motor vehicle claim 1, characterized in that wherein the at least one electric machine comprises at least one electric machine assigned to the rear axle.

4. The motor vehicle of claim 1, wherein the fuel tank and the electric energy accumulator are jointly coolable.

5. The motor vehicle of claim 4, wherein the fuel tank and the electric energy accumulator are positioned as a unit of modular construction in the common section of the body.

6. The motor vehicle of claim 1, wherein the electric energy accumulator is a flywheel accumulator.

7. The motor vehicle of claim 1, wherein the electric energy accumulator is a battery.
